Thanks for replying to my post. The 3rd party app uses a different IDP (Identity Provider) whereas my 2 applications use Discourse. With my current scenario if I want to integrate 3rd party app I have to integrate with its corresponding IDP, since we implemented Discourse for having common login for both the applications ,the login page of Discourse comes in-between where its required to enter credentials and click on Login manually.
Inorder to integrate the 3rd party app I need to skip this manual login part. Just wanted to know whether is this possible or not.
—Thanks.
